COMBINED ROPEWAY.

Specification of Letters latent.

Patented. Sept. 5, 1916.

To all whom it may concern:

Be it known that I, PHILIP B. VVALLACE, a citizen of the United States,residing at the city of San Francisco, in the county of San Franciscoand State of California, have invented certain new and usefulImprovements in Combined Ropeways, of which the following is aspecification.

My invention relates to improvements in ropeways.

The object of my invention is to provide a ropeway having an improvedcarrier supporting a container for containing the load whereby the sameis dumped with certainty and expeditiously on contact with a suitablebumper.

My invention consists in the combination and arrangement of parts shownin the accompanying drawings, described in the following specification,and claimed in the appended claims.

Iteferring to said drawings, Figure 1 is a side view of the carrier andbucket employed in the apparatus; Fig. 2 is an edge view of saidcarrier; Fig. 3 is a View similar to that shown in Fig. 1, but showingthe bucket in the dumping position, and Fig. 4 is an end view of thebumper employed in said apparatus.

In said figures 2 represents a cable. Carrier 6 is supported on cable 2by sheaves 9 mounted thereon and has depending therefrom block 13 fromwhich is supported by chains dumping bucket 16, said bucket beingsecured on one end thereof by chains 15 while the other end thereof isheld by chain 1.5 detachably supported by finger 17 pivoted to block 13.A tripping bumper 44 is attached for the operation to cable 2 at thepoint where the dumping of the bucket or container 16 is desired. Thecarrier 6 on cable 2 to convey the material to the dumping point isactuated by gravity when released by a suitable holding device until thecarrier arrives at the tripping bumper 44, when the load of material insaid bucket is dumped by contact of the container therewith. The dumpingof bucket 16 attached by back chains 15 and front chains 15 to carrierblock 13 is effected by the breaking of the toggle 18 by the striking ofsaid toggle near its center by the lug 49 of bumper 44, which bumper 44is attached to cable 2 for the operation at the point where the dumpingof bucket or container 16 is desired. The striking of the toggle 18 isdone by the movement of carrier 6, from which block 13 is suspended onthe cable 2, toward bumper 44 till contact between said lug 49 and thetoggle occurs. The breaking of said toggle causes the raising of forkedarm 41 connected by pivot 42 to block 13 as a center of rotation andpermits the finger l7 engaging roller 45 secured in the apex of theforks of forked arm 41 to fall by rotation on the pivot 46 and therebyreleasing the upper ring 52 of the front chain 15 as secured at 53, andpermitting the fall of one end of the bucket 16 as held by said frontchain and the consequent emptying of the bucket.

In my improved carrier for ropeways I prefer to employ rollers 9upwardly pivoted thereto so that the same may travel on cable 2; andcable 10 is secured to said carrier by bolt 14, then passes downwardlyunder sheave 12 pivoted to block 13, then passes upwardly over sheave 11pivoted to said carrier toward a suitable drum for winding the same sothat the block can be lowered from the carrier when pin 24 is releasedby pivoted latch 23, which is held up by means of a roller 22 pivoted tothe releasing hook 19. By the pulling of said hook on pin 20 in slot21of said carrier the latch 23 may be released from said roller 22. Hook19 has notches as shown for holding the same, including notch 25.

The bumper 44 may be secured to the cable 2 by a screw or other suitablemeans so that the same may be moved to any position on the cable 2 belowwhich it is desired to empty the container 16.

The hook 19 for holding the carrier is provided with a pin 20 centrallysecured therein and slidable within the slot 21 of the plates or sidewalls of the carrier 6. The carrier has bar 50 for engaging the notchesshown in proximity thereto. The pin 20 being secured to and forming partof bar or hook 19, shown in dotted lines, may be moved to the right inslots 21 in the walls of carrier 6 so as to release roller 22 from latch23, thereby permitting the lowering of the fall block shown. The bar 19has an inclined surface 51 for engaging a suitable holding device. Thecontact of carrier 6 with bumper 4A forces bar 19 to the right as shownin Fig. 3.

I claim:

1. In combination with a track, a carrier thereon having a membersuspended therefrom, a support pivoted to said member and having a freeend, a container having one end connected to said member and the otherend provided with a chain engageable' by said support, a bar pivoted toone end of said member and having a lateral projection engageable withthe free end of said support and a toggle secured to said member andpivoted to said bar for the movement of said bar.

2. In combination with a track and a bumper connected to said track andprovided at its lower end with a lug, a carrier on said track having amember suspended therefrom, a support pivoted to said member and havinga free end, a container having one end connected to said member and theother end provided with a chain engageable by said support, a barpivoted to one end of said member and having a lateral projectionengageable with the free end of said support and a toggle secured tosaid member and pivoted to said bar for the movement of said bar uponthe engagement of said toggle with said lug.

In testimony whereof I afiix my signature in presence of two witnesses.
